Just disconnect the torque tube and the driveshaft, then pull the transmission. That big hole at the bottom of the bellhousing is there to allow you to remove and replace the clutch and pressure plate. No need to remove the bellhousing- - - -in fact, it can't be unbolted from the block without removing the pressure plate, clutch, and flywheel first. I think the flat rate labor time on a clutch change was just about 2 1/2 hours or less back when I was working for a living.
